No problems with installation. A couple of tips.......use a flat blade screwdriver in union with needle nose pliers to get the plastic covers off, it's pretty easy. The other tip, tighten the Torx and Hex head bolts underneath BEFORE you install them in the roof rails, it'll make things much easier.I just picked up mine from the dealer today. Retail was $255......I used my Chevy Points and only ended up paying $160. Good times. I'll see how the installation goes later this afternoon. Fingers crossed.
